Tìm x, biết: h) 5/6 - |2 - x| = 1/3; i) |x - 2/5| + 1/2 = 3/4; k) -2.5 + |3x + 5| = -1/5; m) 1/5 -|1/5 - x| = 1/5
Bài 1 tìm x a)|x| = 5.6 b) |x| = 0 c) |x| = 3/1/5 d) |x| = -2.1
e) |x+3/5|=5 f) |x + 3/4 | - 1/2 = 0 g)|4x | - | -13,5| = |2/1/4 |
h) 5/6 - |2-x| = 1/3 i) |x-2/5| + 1/2 = 3/4 k) -2.5 + |3x +5| = -1/5
m) 1/5 - |1/5 -x| =1/5 n) |5-3x| + 2/3 =1/6 o)(x-2)^2 = 1
p) (2x-1 )^3 = -27
